I don't mind snow, cold, cool or cold rain and wind at all...
The only time I won't go shooting blackpowder is when it gets above 95F outside. When sweat pours in glasses down your shirt just from toting guns from the car to the bench in the shade, I'm going home.
If you can shoot a muzzleloader in that kind of heat and above, you're a fanatic! I'll never be there!
Bring on the cold boys!!!
